BS ISO 9211-1:2018 pdf free.Optics and photonics – Optical coatings
This document defines terms relevant to optical coatings. These terms are grouped in four classes:Terms and definitions, definition of coatings by function, definitions of common coating imperfections and other definitions.
This document identifies surface treatments of components and substrates excluding ophthalmic optics (spectacles) by the application of optical coatings and gives a standard form for their specification. It defines the general characteristics and the test and measurement methods whenever necessary, but is not intended to define the process method.
The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

application of a coating of material(s) intended to modify the optical, physical or chemical characteristics originally possessed by the surface of a component
Note 1 to entry: The substrates are considered to be geometrically perfect and optically homogeneous. In reality,an assembly made up of a substrate and a coating is identified and measured experimentally as an entity.
polarization where the orientation of the electric field vector remains constant
Note 1 to entry: S-polarization refers to linear polarization where the electric field vector is perpendicular to the plane of incidence.
Note 2 to entry: P-polarization refers to linear polarization where the electric field vector is parallel to the plane of incidence.
property of electromagnetic radiation in which the electric field vector rotates about the direction of propagation at the radiation frequency and periodically oscillates in amplitude in a homogeneous optical medium
Note 1 to entry: The terminal point of the electric field vector describes an ellipse.[SOURCE: ISO 11145:2018, 3.12.3]
state in which a beam of electromagnetic radiation is composed of two linearly polarized beams of electromagnetic radiation having orthogonal fixed polarization directions and having amplitudes that vary randomly over time with respect to each other[SOURCE: ISO 11145:2018, 3.12.7]
radiation which has been resolved into any pair of orthogonal electric field vectors with varied phase difference where the average magnitudes of the two orthogonal vectors are the same and their phase difference change is completely random.BS ISO 9211-1 pdf free download.
